Abstract
The utility model relates to a novel block is prevented to high adaptive highway guardrail, including front panel, roof, rear panel and bottom plate. Roof and floor width dwindle with trapezoidal on one side of the stand by being close to a guardrail board side direction gradually, and the rear panel part is formed by stacking two joints of steel sheet to processed the through -hole in stack department, be used for fixing and prevent block, prevented that block is formed by the curved system of monoblock steel plate stamping. The utility model discloses simple structure, easily processing, but self -adaptation lifting height, it is strong to absorb collision energy ability, can use with the guardrail of present form is supporting.
Description
Technical field
The utility model relates to highway barrier component, specifically a kind of novel high self adaptation highway barrier obstruction block.
Background technology
Highway barrier is made up of guardrail board, obstruction block, column, connecting bolt, and wherein obstruction block is fixed between guardrail board and column, is an energy absorbing component.Hexagon is adopted according to " highway traffic safety facilities design specification " obstruction block great majority.But, hexagon obstruction block is when collision happens, make obstruction block can not lifting guardrail height because connecting bolt and column firm is connected, effectively cannot block accident vehicle, easily make accident vehicle cross guardrail run-off-road, wherein one of reason is the difference in height between centre of gravity of vehicle and rum point.Existing height adaptive guardrail board, unstable properties is as uncertain in bending position during collision, can not the effective problem such as lifting guardrail height.
Summary of the invention
In order to overcome existing guardrail obstruction block Problems existing, the utility model provides a kind of novel high self adaptation highway barrier obstruction block, can effective energy absorption when colliding to solve, alleviate impact strength, again can and promote guardrail board height by roof deformation, reduce the difference in height between rum point on vehicle's center of gravity and guardrail, reduce vehicle and cross the run-off-road possibility of guardrail.
The technical scheme that the utility model adopts for its technical problem of solution is: a kind of novel high self adaptation highway barrier obstruction block, comprises front panel, top board, rear board and base plate; The width of top board by near guardrail board one laterally closer column side trapezoidally to reduce gradually, the width of base plate reduces with trapezoidal gradually by near guardrail board one laterally closer column side; Rear board is formed by stacking by two joints of steel plate, and at superposition place processing through hole, for installing obstruction block; Obstruction block is bent by monoblock steel plate punched and forms.
The beneficial effects of the utility model are, structure is simple, be easy to processing, can adaptive boosting height, absorb collision energy ability strong, can support the use with the guardrail of existing form.
Accompanying drawing explanation
Fig. 1 is the structural representation that novel high self adaptation highway barrier obstruction block is installed in highway barrier.
Fig. 2 is a kind of perspective view of novel high self adaptation highway barrier obstruction block.
Fig. 3 is a kind of front view of novel high self adaptation highway barrier obstruction block.
In figure, 1-guardrail board, 2-obstruction block, 2-1-front panel, 2-2-top board, 2-3-rear board, 2-4-base plate, 3-column, 4-long connecting bolt, 5-short connecting bolt.
Detailed description of the invention
Further illustrate the utility model below in conjunction with accompanying drawing, example, only for explaining the utility model, is not intended to limit scope of the present utility model.
As shown in Figure 1, highway barrier is made up of guardrail board (1), obstruction block (2), column (3), long connecting bolt (4), short connecting bolt (5), obstruction block (2) also passes through the top that long connecting bolt (4) is arranged on column (3), and guardrail board (1) is arranged on obstruction block (2) by short connecting bolt (5).
In embodiment as shown in Figure 2 and Figure 3, obstruction block (2) comprises front panel (2-1), top board (2-2), rear board (2-3) and base plate (2-4); Through hole is machined, for installing guardrail board (1) in the middle of front panel (2-1); The width of top board (2-2) reduces with trapezoidal gradually by near guardrail board (1) laterally closer column (3) side; Rear board (2-3) is formed by stacking by two joints of steel plate, and at superposition place processing through hole, for installing obstruction block (1); The width of base plate (2-4) reduces with trapezoidal gradually by near guardrail board (1) laterally closer column (3) side; Obstruction block (2) is bent by monoblock steel plate punched and forms.
In collision process, vehicle first touches guardrail board (1), the impact force of vehicle is delivered to guardrail board (1), then guardrail board (1) extrudes to obstruction block (2), because the width of top board (2-2) near guardrail board (1) side is greater than the width near column (3) side, the width of base plate (2-4) near guardrail board (1) side is greater than the width near column (3) side, top board (2-2) and the intensity of base plate (2-4) near guardrail board (1) side are higher than close column (3) side, therefore top board (2-2) and base plate (2-4) are all first deforming near column (2) side, simultaneously because top board (2-2) and base plate (2-4) all have an inclination angle upwards, the turning that top board (2-2) and base plate (2-4) all lean around nearly column (3) side in collision process is upwards rotated, and drive front panel (2-1) upwards lifting, thus drive guardrail board (1) upwards lifting, the height lifting caused because of ascendant trend during to ensure the height of guardrail board (1) and vehicle collision guardrail is consistent, reduces vehicle and crosses the run-off-road possibility of guardrail.
The technology contents do not addressed in aforesaid way is taked or uses for reference prior art to realize.
